Many of Lichfield’s themes concern the mysteries of Paris and its people. Who is responsible for the city’s extraordinary plumbing? How can you drive around the Arc de Triomphe and survive? He also ponders the phenomena that intrigue many foreigners, such as the eloquence of the capital’s beggars and the identity of the intimidating but fast disappearing concierge. Visiting places as different as the Musée d’Orsay and Disneyland, he explores culture high and low as well as the everyday pleasures and problems of living in Paris.
